Description

Technical Field

[0001] The utility model relates to the technical field of environmental protection, in particular to a desulfurization device. Background Art

[0002] H2S is a highly toxic acidic gas. Excessive H2S content can aggravate corrosion and scaling of the tubing, threatening production safety. Therefore, a desulfurization device is required to treat it. Desulfurization can be carried out using solid or liquid desulfurizers.

[0003] Patent publication number CN213408235U discloses a desulfurization device, which uses a solid desulfurizer to desulfurize flue gas. During desulfurization, the flue gas enters the tank through the air inlet, and the large volume of flue gas is divided by the orifice plate to increase the contact area with the desulfurizer. After division, the flue gas enters the desulfurizer, and the desulfurizer desulfurizes the flue gas. However, long-term use of the desulfurizer to desulfurize the flue gas requires replacement of the desulfurizer after the reaction. It is not convenient to replace the solid desulfurizer after the reaction, and the orifice plate at the lower end is easily clogged with dirt after long-term use, affecting the desulfurization effect. For this reason, we propose a desulfurization device. Utility Model Content

The left and right sides of the tank body 1 are respectively fixedly connected to support legs 4. A partition 5 is fixedly connected to the middle of the tank body 1. An arc-shaped groove 6 is opened on the left side of the partition 5. A vent hole 7 is passed through the middle of the partition 5 in the vertical direction. The vent hole 7 is coaxially arranged with the tank body 1. The vent hole 7 passes through the arc groove 6 in the vertical direction. A turntable 8 is rotatably connected in the arc groove 6.

The bottom end of the tank body 1 is fixedly installed with a first driving mechanism, which is used to drive the turntable 8 to rotate. A scraper 10 is provided inside the lower end of the vent 7. The scraper 10 is used to wipe and clean the dirt adhered to the bottom end of the circular box body 9. The middle part of the bottom end of the scraper 10 is fixedly connected to a rotating shaft 11 coaxial with the tank body 1. The middle part of the bottom end of the tank body 1 is fixedly installed with a second driving mechanism, which is used to drive the rotating shaft 11 to rotate. A blower blade 12 is coaxially fixedly assembled at the bottom end of the tank body 1 and on the outside of the rotating shaft 11;

[0027] The flue gas first enters the tank body 1 through the air intake pipe 3 of this embodiment. During the process, the second driving mechanism is started, and the second driving mechanism drives the blower blades 12 to rotate for blowing. The flue gas flows upward through the vent 7 and the circular box body 9. The orifice plate at the bottom end of the circular box body 9 divides the large volume of flue gas to increase the contact area with the solid desulfurizer. After division, the flue gas enters the solid desulfurizer, and the solid desulfurizer desulfurizes the flue gas. At the same time, the second driving mechanism drives the rotating shaft 11 to rotate, and the rotating shaft 11 drives the scraper 10 to rotate, so that the scraper 10 wipes and cleans the bottom surface of the circular box body 9 to prevent flue gas dirt from clogging the orifice plate at the bottom end of the circular box body 9. After long-term use, when the solid desulfurizer needs to be replaced, the first driving mechanism is started to drive the turntable 8 to rotate 90°, so that the other circular box body 9 on the turntable 8 rotates into the vent 7, thereby completing the replacement of the solid desulfurizer.

In this embodiment, by starting the second motor 15, the rotating shaft 11 is driven to rotate, and the rotating shaft 11 drives the blower blades 12 to rotate, thereby realizing upward blowing of the flue gas. At the same time, the rotating shaft 11 drives the scraper 10 to rotate, and scrapes off the dirt adhered to the orifice plate at the bottom end of the circular box body 9 to prevent the orifice plate at the bottom end of the circular box body 9 from being blocked.
